- Abstract
Integrated Circuits and Electronic Modules experience concentrated thermal hot spots, which require advanced thermal solutions for effective distribution and dissipation of heat. The superior thermal properties of diamonds are long known, and it is an ideal material for heat-spreading applications. However, growing diamond films to the electronic substrate require complex processing at high temperatures. This research investigates a heterogeneous method of integrating diamond heat spreaders during the back-end packaging process. The semiconductor substrate and the heat spreader thicknesses were optimized based on simulations to realize a thermally enhanced Power Quad-Flat No-Lead package. The performance of the thermally enhanced PQFN was assessed by monitoring the temperature distribution across the active device surface and compared to a standard PQFN (without a heat spreader). Firstly, the thermally enhanced PQFN indicated a 9.6% reduction in junction temperature for an input power of 6.6W with a reduced thermal gradient on the active device surface. Furthermore, the diamond heat spreader's efficiency was observed to increase with increasing power input. Besides, the reliability of the thermally enhanced PQFN was tested by thermal cycling from -55°C to 150°C, which resulted in less than 2% thermal degradation over two-hundred cycles. Such choreographed thermal solutions are proven to enhance the packaged device's performance, and the superior thermal properties of the diamond are beneficial to suffice the increasing demand for high power., Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public., Electronic Components, Technology and Materials

- Abstract
Kurs- och läroplaner styr svensk skolas syfte, mål och innehåll. Vår nuvarande läroplan Lgr11 är en lärares främsta styrdokument och jag har velat undersöka vad som står i denna skrivelse avseende kultur med utgångspunkt i moderna språk med fokus på tyska. Den nationella och internationella diskursen kring kultur och språk har ändrats under åren och alltmer kommit att handla om interkulturell kompetens. Frågan är då vad som står i styrdokumenten avseende interkulturell kompetens och hur den ska uppnås. Syftet är att se hur styrdokumenten kan tolkas utifrån denna frågeställning. Jag har gjort en kvalitativ textanalys av den övergripande läroplanen, kursplanen för moderna språk samt kommentarerna till kursplanen. Analysen av texterna är gjord utifrån ett sociokulturellt perspektiv. Jag har funnit att i de undersökta texterna syns en tydlig strävan efter att elever uppnår interkulturell kompetens. Det finns en vision om att elever blir interkulturellt kompetenta medborgare i en global värld. Med utgångspunkt i elevers egna erfarenheter och villkor ska den kulturella kompetensen leda till ökad förståelse och medmänsklighet både nationellt i vårt mångkulturella samhälle och internationellt. Genom att våga göra sin röst hörd på målspråket och genom interkulturell medvetenhet som utgår från demokrati och solidaritet kan eleven interagera och mötas i samhälls- och kulturlivet internationellt.

- Abstract
This paper is dedicated to a detailed analysis and computation of quantum states of causal fermion systems. The mathematical core is to compute integrals over the unitary group asymptotically for a large dimension of the group, for various integrands with a specific scaling behavior in this dimension. It is shown that, in a well-defined limiting case, the localized refined pre-state is positive and allows for the description of general entangled states., Comment: 89 pages, LaTeX, 9 figures, small improvements (published version)

- Abstract
This thesis investigates share buybacks, specifically share buyback announcements. It addresses how to recognize such announcements, the excess return of share buybacks, and the prediction of returns after a share buyback announcement. We illustrate two NLP approaches for the automated detection of share buyback announcements. Even with very small amounts of training data, we can achieve an accuracy of up to 90%. This thesis utilizes these NLP methods to generate a large dataset consisting of 57,155 share buyback announcements. By analyzing this dataset, this thesis aims to show that most companies, which have a share buyback announced are underperforming the MSCI World. A minority of companies, however, significantly outperform the MSCI World. This significant overperformance leads to a net gain when looking at the averages of all companies. If the benchmark index is adjusted for the respective size of the companies, the average overperformance disappears, and the majority underperforms even greater. However, it was found that companies that announce a share buyback with a volume of at least 1% of their market cap, deliver, on average, a significant overperformance, even when using an adjusted benchmark. It was also found that companies that announce share buybacks in times of crisis emerge better than the overall market. Additionally, the generated dataset was used to train 72 machine learning models. Through this, it was able to find many strategies that could achieve an accuracy of up to 77% and generate great excess returns. A variety of performance indicators could be improved across six different time frames and a significant overperformance was identified. This was achieved by training several models for different tasks and time frames as well as combining these different models, generating significant improvement by fusing weak learners, in order to create one strong learner.

- Abstract
Educational Governance beschäftigt sich mit der Handlungsabstimmung im Mehrebenensystem Schule und geht der Frage nach, inwiefern Schnittstellenprobleme bei der Interaktion der Akteure auf den Ebenen auftreten. Der Beitrag fokussiert unter dieser Prämisse die Ebene der Einzelschule und analysiert auf Grundlage von Daten einer bundesweit, quasi-längsschnittlich angelegten Online-Befragung von Schulleitungen, wie diese angesichts der unter dem Druck der Pandemie zunehmenden Dezentralisierung von Gestaltungsverantwortung Schule und Unterricht nach den beiden Lockdowns im März und Dezember 2020 unter den geltenden Bestimmungen des Infektionsschutzes organisiert und welche organisationalen Strukturen sie etabliert haben. Die Auswertungen zeigen, dass das Kollegium, die regionale Bildungsverwaltung und auch regionale Rektor:innenverbünde relevante Austauschpartner:innen für Schulleitungen darstellen. Zudem ist – zumindest kurzfristig – ein Digitalisierungsschub in den Schulen festzustellen, der sich einerseits in der Nutzung digitaler Strukturen (wie z. B. Durchführung von Videokonferenzen) niederschlägt, und der andererseits auf die kooperative Entwicklung von digitalisierten Lernmaterialien zielt. Inwiefern die unter dem Druck der Pandemie emergierenden Veränderungen auch nachhaltig Einfluss auf das Schulleben nach der Pandemie nehmen werden und in «echten» und somit nachhaltigen Schulentwicklungsprozessen verarbeitet werden, wird in der abschliessenden Diskussion aufgegriffen., Educational governance deals with the coordination of actions in the multi-level school system and investigates the extent to which interface problems arise in the interaction of the actors at the levels. Following this premise, the article focuses on the level of the individual school and analyzes on the basis of data from a nationwide, quasi-longitudinal online survey how school principals organize their schools after the re-opening and what external and internal structures the set up, to enable face-to-face classes under the strict infection control measures. The findings show that the teaching staff, as well as regional administration and regional rector associations are relevant exchange partners for school management. In addition, there is a push towards digitization in schools, which is reflected in the use of digital structures (e.g. conducting video conferences) and the cooperative development of digitized learning materials. The extent to which the changes that emerged under the pressure of the pandemic will also have a lasting impact on school life after the pandemic and will be processed in «real» school development processes will be discussed at the end.

- Abstract
Distinct from their contributions to stress granules, G3BPs regulate mTORC1 activity through spatial control of the TSC complex.Ras GTPase-activating protein-binding proteins 1 and 2 (G3BP1 and G3BP2, respectively) are widely recognized as core components of stress granules (SGs). We report that G3BPs reside at the cytoplasmic surface of lysosomes. They act in a non-redundant manner to anchor the tuberous sclerosis complex (TSC) protein complex to lysosomes and suppress activation of the metabolic master regulator mechanistic target of rapamycin complex 1 (mTORC1) by amino acids and insulin. Like the TSC complex, G3BP1 deficiency elicits phenotypes related to mTORC1 hyperactivity. In the context of tumors, low G3BP1 levels enhance mTORC1-driven breast cancer cell motility and correlate with adverse outcomes in patients. Furthermore, G3bp1 inhibition in zebrafish disturbs neuronal development and function, leading to white matter heterotopia and neuronal hyperactivity. Thus, G3BPs are not only core components of SGs but also a key element of lysosomal TSC-mTORC1 signaling.

- Abstract
Objective The study aims to assess changes in HIV treatment outcomes for Jamaica after the implementation of the WHO Treat All strategy in January 2017, as well as identify variables associated with clinical stage at diagnosis and viral load status, in order to understand implications for enhancing the HIV clinical cascade and boosting progress towards the UNAIDS 90-90-90 targets. Method This is a population-based study using the National Treatment Service Information System. The sample consists of persons 15 years and older, placed on treatment before and after Treat All was implemented, across all 4 regional health authorities in Jamaica. Patients were assessed for two binary outcomes: 1. stage at HIV diagnosis (early/baseline CD4 cell count ≧350 cells/mm3, or late/ baseline CD4 <350 cells/mm3), 2. viral load status achieved after ART initiation (suppressed/<1000 copies/ml or non-suppressed/ ≥1000 copies/ml). Categorical variables: age/years, gender and health regions, were investigated using multivariable logistic regression. Adjusted odds ratios and 95% confidence intervals are reported. Results After Treat All, there was an increase in median baseline CD4 results as the proportion of late diagnoses decreased from 60% to 39%. There was a small increase in viral suppression from 76% to 80%, a decrease in baseline viral load testing from 61% to 46% and an increase in the uptake of first viral load testing after starting treatment from 13% to 19%. Males and persons 40+ years had higher odds of late diagnosis before and after Treat All. Conclusion Jamaica’s HIV program outcomes have improved after Treat All was implemented. ART initiation time significantly decreased. Early diagnosis, viral load testing uptake and viral suppression increased. However, there is a need to implement targeted testing for men and persons over 40 years to decrease the frequency of late diagnosis.

Patients were assessed for two binary outcomes: 1. stage at HIV diagnosis (early/baseline CD4 cell count ≧350 cells/mm3, or late/ baseline CD4 <350 cells/mm3), 2. viral load status achieved after ART initiation (suppressed/<1000 copies/ml or non-suppressed/ ≥1000 copies/ml). Categorical variables: age/years, gender and health regions, were investigated using multivariable logistic regression. Adjusted odds ratios and 95% confidence intervals are reported. Results After Treat All, there was an increase in median baseline CD4 results as the proportion of late diagnoses decreased from 60% to 39%. There was a small increase in viral suppression from 76% to 80%, a decrease in baseline viral load testing from 61% to 46% and an increase in the uptake of first viral load testing after starting treatment from 13% to 19%. Males and persons 40+ years had higher odds of late diagnosis before and after Treat All. Conclusion Jamaica’s HIV program outcomes have improved after Treat All was implemented. ART initiation time significantly decreased. Early diagnosis, viral load testing uptake and viral suppression increased. However, there is a need to implement targeted testing for men and persons over 40 years to decrease the frequency of late diagnosis.

- Abstract
Spring phytoplankton blooms in temperate environments contribute disproportionately to global marine productivity. Bloom-derived organic matter, much of it occurring as polysaccharides, fuels biogeochemical cycles driven by interacting autotrophic and heterotrophic communities. We tracked changes in the mode of polysaccharide utilization by heterotrophic bacteria during the course of a diatom-dominated bloom in the German Bight, North Sea. Polysaccharides can be taken up in a ‘selfish’ mode, where initial hydrolysis is coupled to transport into the periplasm, such that little to no low-molecular weight (LMW) products are externally released to the environment. Alternatively, polysaccharides hydrolyzed by cell-surface attached or free extracellular enzymes (external hydrolysis) yield LMW products available to the wider bacterioplankton community. In the early bloom phase, selfish activity was accompanied by low extracellular hydrolysis rates of a few polysaccharides. As the bloom progressed, selfish uptake increased markedly, and external hydrolysis rates increased, but only for a limited range of substrates. The late bloom phase was characterized by high external hydrolysis rates of a broad range of polysaccharides and reduced selfish uptake of polysaccharides, except for laminarin. Substrate utilization mode is related both to substrate structural complexity and to the bloom-stage dependent composition of the heterotrophic bacterial community.

- Abstract
There is a growing consensus that one of the key priorities to address food and nutrition security is to aim at the transformation of agriculture and food systems. The private sector can fulfil an important role in this. It is often argued that the success at low income markets (denoted here as Bottom of the Pyramid - BOP) requires innovative and inclusive business models. However, research findings on this have been quite descriptive and generic. The literature on private sector engagement and food and nutrition security has a strong focus on the participation of businesses in the value chain and the food system, but does generally not unravel the specific characteristics of the inclusive business model itself. This article aims to contribute to an improved understanding with regard to inclusive business model characteristics of private sector interventions aiming at food and nutrition security improvements, by scrutinizing 16 cases from Africa, Asia and Latin America. The study focuses on the internal fitness of the strategic business model by analysing the foundation level components of the inclusive business model. Important findings are the relevance of quality of product or service besides its affordability, marketing and distribution strategies to link the different actors in the value chain, and training as well as coalition building to overcome institutional and cultural gaps and increase the success of the inclusive business model for improved nutrition and food security. An important conclusion is that the business model and business ecosystem of BOP markets is crucial. Also, the findings indicate a need for intermediaries to overcome cultural and institutional gaps in implementing inclusive business models.

- Abstract
Introduction While university students are known to face major life transition challenges with the risk to engage in potentially undesirable health-related habits, there are very few attempts to monitor students’ health behaviour on a regular long-term basis. Even in cross-sectional designs, students from the field of Public Health and/or Health Sciences are rarely investigated. Here, a cross-university students’ health behaviour surveillance system is presented. Methods A students’ health and health behaviour surveillance system (SuSy) has been implemented in Hamburg University of Applied Sciences in 2014, collecting and analysing data of health sciences students twice a year since. After Manchester Metropolitan University joined the project and adapted SuSy to its specific context in 2016, data of both SuSy settings were compared using logistic regression models. In addition, focus groups were carried out in both universities in order to assess the perception and acceptance of the tool. Results After eight elicitations with total sample of 1366 responses, a decreasing trend of smoking and increasing trend of cannabis consumption can be observed among Hamburg students. In comparison, Manchester students tend to smoke significantly more (OR = 3.74, 95%CI 1.95-7.17), but consume less cannabis (OR = 0.51, 95%CI 0.14-0.9). Trends in physical activity and healthy food consumption complete the overview. Focus groups revealed that SuSy is perceived as an appealing, useful and recognisable tool among students from both universities. Discussion While being easily adapted in content and delivery, SuSy allows for the provision helpful, comparable information about students’ health behaviours as well as for the observation of time trends. These findings underline SuSy’s potential in promoting university students’ health.

- Abstract
Osteogenesis imperfecta (OI) comprises a genetically heterogeneous group of skeletal fragility diseases. Here, we report on five independent families with a progressively deforming type of OI, in whom we identified four homozygous truncation or frameshift mutations in MESD. Affected individuals had recurrent fractures and at least one had oligodontia. MESD encodes an endoplasmic reticulum (ER) chaperone protein for the canonical Wingless-related integration site (WNT) signaling receptors LRP5 and LRP6. Because complete absence of MESD causes embryonic lethality in mice, we hypothesized that the OI-associated mutations are hypomorphic alleles since these mutations occur downstream of the chaperone activity domain but upstream of ER-retention domain. This would be consistent with the clinical phenotypes of skeletal fragility and oligodontia in persons deficient for LRP5 and LRP6, respectively. When we expressed wild-type (WT) and mutant MESD in HEK293T cells, we detected WT MESD in cell lysate but not in conditioned medium, whereas the converse was true for mutant MESD. We observed that both WT and mutant MESD retained the ability to chaperone LRP5. Thus, 01-associated MESD mutations produce hypomorphic alleles whose failure to remain within the ER significantly reduces but does not completely eliminate LRP5 and LRP6 trafficking. Since these individuals have no eye abnormalities (which occur in individuals completely lacking LRP5) and have neither limb nor brain patterning defects (both of which occur in mice completely lacking LRP6), we infer that bone mass accrual and dental patterning are more sensitive to reduced canonical WNT signaling than are other developmental processes. Biologic agents that can increase LRP5 and LRP6-mediated WNT signaling could benefit individuals with MESD-associated OI.

- Abstract
The South Pacific Gyre (SPG) covers 10% of the ocean’s surface and is often regarded as a marine biological desert. To gain an on-site overview of the remote, ultraoligotrophic microbial community of the SPG, we developed a novel onboard analysis pipeline, which combines next-generation sequencing with fluorescence in situ hybridization and automated cell enumeration. We tested the pipeline during the SO-245 “UltraPac” cruise from Chile to New Zealand and found that the overall microbial community of the SPG was highly similar to those of other oceanic gyres. The SPG was dominated by 20 major bacterial clades, including SAR11, SAR116, the AEGEAN-169 marine group, SAR86, Prochlorococcus, SAR324, SAR406, and SAR202. Most of the bacterial clades showed a strong vertical (20 m to 5,000 m), but only a weak longitudinal (80°W to 160°W), distribution pattern. Surprisingly, in the central gyre, Prochlorococcus, the dominant photosynthetic organism, had only low cellular abundances in the upper waters (20 to 80 m) and was more frequent around the 1% irradiance zone (100 to 150 m). Instead, the surface waters of the central gyre were dominated by the SAR11, SAR86, and SAR116 clades known to harbor light-driven proton pumps. The alphaproteobacterial AEGEAN-169 marine group was particularly abundant in the surface waters of the central gyre, indicating a potentially interesting adaptation to ultraoligotrophic waters and high solar irradiance. In the future, the newly developed community analysis pipeline will allow for on-site insights into a microbial community within 35 h of sampling, which will permit more targeted sampling efforts and hypothesis-driven research.

- Abstract
The South Pacific Gyre (SPG) covers 10% of the ocean’s surface and is often regarded as a marine biological desert. To gain an on-site overview of the remote, ultraoligotrophic microbial community of the SPG, we developed a novel onboard analysis pipeline, which combines next-generation sequencing with fluorescence in situ hybridization and automated cell enumeration. We tested the pipeline during the SO-245 “UltraPac” cruise from Chile to New Zealand and found that the overall microbial community of the SPG was highly similar to those of other oceanic gyres. The SPG was dominated by 20 major bacterial clades, including SAR11, SAR116, the AEGEAN-169 marine group, SAR86, Prochlorococcus, SAR324, SAR406, and SAR202. Most of the bacterial clades showed a strong vertical (20 m to 5,000 m), but only a weak longitudinal (80°W to 160°W), distribution pattern. Surprisingly, in the central gyre, Prochlorococcus, the dominant photosynthetic organism, had only low cellular abundances in the upper waters (20 to 80 m) and was more frequent around the 1% irradiance zone (100 to 150 m). Instead, the surface waters of the central gyre were dominated by the SAR11, SAR86, and SAR116 clades known to harbor light-driven proton pumps. The alphaproteobacterial AEGEAN-169 marine group was particularly abundant in the surface waters of the central gyre, indicating a potentially interesting adaptation to ultraoligotrophic waters and high solar irradiance. In the future, the newly developed community analysis pipeline will allow for on-site insights into a microbial community within 35 h of sampling, which will permit more targeted sampling efforts and hypothesis-driven research.

- Abstract
Osteogenesis imperfecta (OI) comprises a genetically heterogeneous group of skeletal fragility diseases. Here, we report on five independent families with a progressively deforming type of OI, in whom we identified four homozygous truncation or frameshift mutations in MESD. Affected individuals had recurrent fractures and at least one had oligodontia. MESD encodes an endoplasmic reticulum (ER) chaperone protein for the canonical Wingless-related integration site (WNT) signaling receptors LRP5 and LRP6. Because complete absence of MESD causes embryonic lethality in mice, we hypothesized that the OI-associated mutations are hypomorphic alleles since these mutations occur downstream of the chaperone activity domain but upstream of ER-retention domain. This would be consistent with the clinical phenotypes of skeletal fragility and oligodontia in persons deficient for LRP5 and LRP6, respectively. When we expressed wild-type (WT) and mutant MESD in HEK293T cells, we detected WT MESD in cell lysate but not in conditioned medium, whereas the converse was true for mutant MESD. We observed that both WT and mutant MESD retained the ability to chaperone LRP5. Thus, 01-associated MESD mutations produce hypomorphic alleles whose failure to remain within the ER significantly reduces but does not completely eliminate LRP5 and LRP6 trafficking. Since these individuals have no eye abnormalities (which occur in individuals completely lacking LRP5) and have neither limb nor brain patterning defects (both of which occur in mice completely lacking LRP6), we infer that bone mass accrual and dental patterning are more sensitive to reduced canonical WNT signaling than are other developmental processes. Biologic agents that can increase LRP5 and LRP6-mediated WNT signaling could benefit individuals with MESD-associated OI.

- Abstract
One important advantage of Additive Manufacturing (AM) in relation to optimization for light weight construction is that there is a reduction in manufacturing constraints compared to classical manufacturing methods [5]. To make full use of these advantages and to exploit the resulting potential, the components previously have to be designed using optimization (see[5]). Against this backdrop, a Mixed Integer Program (MIP) is developed in order to be able to use the methods of Technical Operations Research (TOR) in the context of Topology Optimization (TO) on the basis of a fitted Ground Structure Method (GSM) for lattice and truss structures. In addition, an optimization-oriented construction workflow (see figure 3) is developed in order to fully exploit the advantages in design freedom of AM. As shown in figure 3, this work addresses three interdisciplinary subareas; Operations Research (OR), AM as the manufacturing method and a link between this sub-areas in the form of a Computer Aided Design (CAD) solution, resulting in a TOR application.

- Abstract
Background: Chronic hepatitis B (CHB) related morbidity and mortality can be reduced through risk group screening, linkage to care and anti-viral treatment. This study estimates the number of CHB cases among foreign-born (migrants) in the European Union and European Economic Area (EU/EEA) countries in order to identify the most affected migrant populations. Methods: The CHB burden was estimated by combining: demographic data on migrant population size by country of birth in the EU/EEA, extracted from European statistical databases; and CHB prevalence in migrants' countries of birth and in EU/EEA countries, derived from a systematic literature search. The relative contribution of migrants from endemic countries to the total CHB burden in each country was also estimated. The reliability of using country of birth prevalence as a proxy for prevalence among migrants was assessed by comparing it to the prevalence found in studies among migrants in Europe. Results: An estimated 1-1.9 million CHB-infected migrants from endemic countries (prevalence ≥2%) reside in the EU/EEA. Migrants from endemic countries comprise 10.3% of the total EU/EEA population but account for 25% (15%-35%) of all CHB cases. Migrants born in China and Romania contribute the largest number of infections, with over 100,000 estimated CHB cases each, followed by migrants from Turkey, Albania and Russia, in descending order, with over 50,000 estimated CHB cases each. The CHB prevalence reported in studies among migrants in EU/EEA countries was lower than the country of birth prevalence in 9 of 14 studies. Conclusions: Migrants from endemic countries are disproportionately affected by CHB; their contribution however varies between EU/EEA countries. Migrant focused screening strategies would be most effective in countries with a high relative contribution of migrants and a low general population prevalence. In countries with a higher general population prevalence and a lower relative contribution of migrant

- Abstract
Background: Renal cell carcinoma is among the most prevalent malignancies. It is generally sporadic. However, genetic studies of rare familial forms have led to the identification of mutations in causative genes such as VHL and FLCN. Mutations in the FLCN gene are the cause of Birt-Hogg-Dube syndrome, a rare tumor syndrome which is characterized by the combination of renal cell carcinoma, pneumothorax and skin tumors. Methods: Using Sanger sequencing we identify a heterozygous splice-site mutation in FLCN in lymphocyte DNA of a patient suffering from renal cell carcinoma. Furthermore, both tumor DNA and DNA from a metastasis are analyzed regarding this mutation. The pathogenic effect of the sequence alteration is confirmed by minigene assays and the biochemical consequences on the protein are examined using TALEN-mediated transgenesis in cultured cells. Results: Here we describe an FLCN mutation in a 55-year-old patient who presented himself with progressive weight loss, bilateral kidney cysts and renal tumors. He and members of his family had a history of recurrent pneumothorax during the last few decades. Histology after tumor nephrectomy showed a mixed kidney cancer consisting of elements of a chromophobe renal cell carcinoma and dedifferentiated small cell carcinoma component. Subsequent FLCN sequencing identified an intronic c.1177-5_-3delCTC alteration that most likely affected the correct splicing of exon 11 of the FLCN gene. We demonstrate skipping of exon 11 to be the consequence of this mutation leading to a shift in the reading frame and the insertion of a premature stop codon. Interestingly, the truncated protein was still expressed both in cell culture and in tumor tissue, though it was strongly destabilized and its subcellular localization differed from wild-type FLCN. Both, altered protein stability and subcellular localization could be partly reversed by blocking proteasomal and lysosomal degradation. Conclusions: Identification of disease-causing mu

- Abstract
Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic cause of dialysis-requiring end-stage renal disease in adults and is characterized by the slowly progressing replacement of renal tissue by focal macrocysts. Alport syndrome (AS; hereditary nephritis) is a rare, inherited disorder of the basement membrane associated with hematuria, proteinuria, and loss of kidney function as well as sensorineural hearing loss and ocular abnormalities. Here, we report on a family in which both ADPKD and AS are present. In a male patient, both - ADPKD and AS coincided. This patient shows the very rare coexistence of two severe, inherited renal disorders and illustrates the importance of considering additional diagnoses in the setting of positive family history for a common hereditary disorder.
